Of the 148 stocks with 20% or more of their sales sold short, 115 of them (77%) are trading higher today, a day when the broad market indexes themselves are tumbling by several hundred points. Even more notable, fully one-third of the heavily shorted issues are up by double-digit percentage rates today. Now what The high volatility is common in these situations, but because the trading action is divorced from the company's fundamentals, it is a fleeting trend that can't last. Eventually the short-sellers cover their positions and the stocks return to earth, often just as dramatically as they soared. Investors shouldn't be swayed by these price swings, and investors would be smart to sit on the sidelines until GSX Techedu sorts out the battle taking place between short-sellers and those long on its stock. 10 stocks we like better than GSX Techedu Inc.When investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
